Default P0300 Misfire Freeze Frame Data

I bought a 2010 370z a couple of months ago. The 2nd day i drove it the CEL came on. I had AutoZone read the codes and it was a P0300. I read up on it and bought new coil packs and spark plugs. I replaced them and the code came back on. I have looked for vacuum leaks and check all the hoses. I bought an Innova 5410 scanner and plugged it in. It read the same code as before and i downloaded the freeze frame data. I have tried to google as much as i could about what everything means but i just can't find anything with the same format as what the scanner put out. If anyone could look over this data and let me know if something doesn't look right or if anyone has the time to kind of explain what everything means, I would really appreciate it. Thank you in advance.
